Note to promoters: do not ever pull the plug on Foo Fighters when they're jamming. Over the weekend at Bottlerock, the Foos were in the middle of "Everlong" when they passed the area's strict curfew time. The festival pulled the plug on Dave Grohl and company, but that didn't stop them from continuing to power through the song. 

Watch above to see what happens when you try to stop the Foo Fighters.
